Farhad Faramarzi is a Mining Engineer (BEng, MEng) with expertise in drilling and blasting. He has worked  as a D&B superintendent Engineer and designed, managed and surveyed over 100 full-scale production blasts at some large iron and copper open-pit mines in Iran. Farhad recently completed his PhD at JKMRC, titled “The Measurement of Variability in Ore Competence and its Impact on Process Performance” and is currently working within the IES team at CRC ORE as a mining and process engineer.

For decades the minerals industry has been challenged by inherent variability of ore deposits. Quantifying this characteristic of orebodies and estimating its impact on the process performance is becoming increasingly important b . Ore comminution is the most energy-intensive process in almost all mines and requires designs specifically tailored to aid maximising the value chain. Although ore variability is frequently debated as a major source of uncertainty in process performance, most of the current ore testing methods do not capture this variability and plant designs and process performance predictions are based on using average values for ore characteristics. Recently, a novel drop weight testing approach (ExDWT) has been developed at The University of Queensland’s Julius Kruttschnitt Mineral Research Centre, that measures the extent of ore competence variability within “representative” samples. In this presentation, Farhad will share the understanding gained from conducting the ExDWT approach on a wide range of rock types.
